The invention discloses a single-oil-way forward variable pitch mechanism propeller. A plurality of propeller sleeves are evenly distributed on a propeller shell assembly. A propeller root centering hole penetrates through the centering shaft, the end face of the propeller root centering hole is in butt joint with the end face of the propeller sleeve and is clamped and fixed together through a hoop which is in clearance fit with the outer wall of the propeller sleeve and is in close fit with the propeller root, a sealing ring and a split thrust ball bearing are installed between the hoop and the propeller sleeve, and a needle bearing is installed between the propeller root centering hole and the centering shaft. The rear end of a cylinder cup of which the front end wall is provided with anannular boss and more than three mounting holes for fixing feathering limiters is fixed in the front end wall of the propeller shell assembly; the rear end of the piston sleeving the cylinder cup isfixed on the side wall of the front end part of the propeller shell assembly; the lubricating oil pipe penetrates through the annular boss of the cylinder cup and the central hole of the piston to behermetically locked and fixed on the front end wall of the piston; a reverse paddle limiting pipe and an adjusting washer are sleeved on the lubricating oil pipe; and feathering springs are sleeved onthe excircles of the lubricating oil pipe, the reverse propeller limiting pipe and the cylinder cup annular boss. The single-oil-way forward variable pitch mechanism propeller is simple in structure,light in weight, small in size, high in safety coefficient and easy to install and maintain.

    本发明公开了一种单油路正向变距机构螺旋桨,桨壳组件上均布有多个桨袖;桨根定心孔穿在定心轴上,其端面与桨袖端面对接,通过与桨袖外壁间隙配合、与桨根紧配合的卡箍卡紧固定在一起,在卡箍与桨袖之间安装有密封圈和剖分式推力球轴承,在桨根定心孔与定心轴之间安装有滚针轴承;前端壁有环型凸台和三个以上固定顺桨限动件的安装孔的缸杯后端固定在桨壳组件前端壁内;活塞套在缸杯的外,后端固定在桨壳组件前端部侧壁上;滑油管穿越缸杯环型凸台和活塞中心孔密封锁紧固定在活塞前端壁上;在滑油管上套有反桨限动管和调整垫圈;滑油管、反桨限动管和缸杯环型凸台外圆上套有顺桨弹簧。本发明结构简单,质量轻,体积小,安全系数高,安装维修简单。
